Specification of Letters Patent. Application flledflpril 22, 1910.Serial No. 557,038.

Patented June 3, 1913.

To all whom it may concern Be it known that I, LIVINGSTON A. THOMP- soN,a citizen of the United States, residing at Milwaukee, State ofWisconsin, have invented a new and useful Improvement in ConcentratedFood Products, of which the following is a specification.

The object of this invention is to provide a concentrated food of greatnutritive power and one especially adapted for use in the feeding ofenemies and those of backward growth and at the sametime minimize thecost of production of such food.

The resent invention seeks to provide such a ood which will be rich withiron in the most highly complex and organic form in order that it may bereadily used for the formation of new hemoglobin molecules inthe bloodof the patient and at the Sam:- time will be of great food value both asa heat producer and as a tissue builder.

The concentrated food of this invention is produced b first treatingfresh blood in order to brea up thered blood corpuscles thereof so thatthe hemoglobin solution may pass out. This rupture of the blood cells Amay be accomplished by various means, as

by the repeated freezing and thawing of the blood, or by a treatmentwith chemicals, such as ether, alcohol, etc., but preferably by addingwater to the blood and allowing it to stand for a sufiicient time toaccomplish the purpose.

3 to 6 hours in 200 pounds of water. The blood so treated is thensubjected to a digestive process, first being warmed to about 90 degreesFahrenheit at which tem erature the. digestive process will be more eective. Approximately 6 drains of scale pepsin and the same amount ofpapein is dissolved in water and then added to the blood and water andmixed therewith where it is allowed to act until digestion is completed,usually for about six hours, the mass in the meantime being retained ata temperature of a proximately 100 degrees Fahrenheit an beingconstantly agitated. The digested blood is next filtered to remove solidmatter therefrom and constitutes the main ingredient of Usually 48pounds of fresh blood is allowed to stand from the product, a starchygrain, such as wheat, and preferably the flour thereof which may be lessexpensive, is mixed with malt, usually barley malt, and allowed to standat'a suitable temperature to produce malted starch. For the quantity ofdigested blood above given, it is desirable to use approximately 10pounds of wheat flour and 25 pounds of barley malt which are allowed tostand in a solution of water at a temperature of 165 degrees Fahrenheitfor about three hours, or until all the starch is digested and theliquid will not turn blue with the iodin test. This malt solution isthen strained to remove the husks and is mixed with the digested bloodand the mixture of these two is reduced to a dry form in a vacuum pan orby other process of evaporation and then pulverized to a owder.

When it is desired to inc ude milk as an ingredient of the preparation,it may be added to the mixture of the digested blood and malted starchbefore the evaporation process.

The powder product may be prepared for use by dissolving in water ormilk and flavoring to suit the taste.

What I claim as new and desire to secure by Letters Patent is:

1. A concentrated dry food product composed of digested blood and maltsugar.

- 2. A concentrated dry food product composed of digested blood, sugarand milk.

'3. The herein described method of preparing a concentrated food productwhich consists in first digesting blood by breaking open the redcorpuscles thereof and subjecting it to the action of pepsin and papein,then adding sugar thereto in the torm of a solution produced by allowingwheat flour and barley malt to stand together in water until the starchis digested, and then evaporating such mixture to a dry form.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
